Method to operate parallel bypass thyristors at low load

A non-transitory computer-readable medium containing computer-readable instructions for a power system, the instructions instructing at least one processor to:

• responsive to an input current being provided to a first thyristor, control a current source coupled between a second thyristor and an output, the current source coupled in a shunt configuration with respect to the second thyristor and a reference node, to provide a biasing voltage across the second thyristor to induce a change in a voltage across the second thyristor from a first voltage to a second voltage, the second voltage being greater than a threshold voltage of the second thyristor.

A method of operating a first thyristor and a second thyristor coupled in parallel, the method comprising:

• providing a voltage associated with a current to the first thyristor and the second thyristor;
• and
• providing, via a current source coupled between the second thyristor and an output, the current source coupled in a shunt configuration with respect to the second thyristor and a reference node, a biasing voltage across the second thyristor to induce a change in a voltage across the second thyristor from a first voltage to a second voltage, the first voltage being less than a threshold voltage of the second thyristor and the second voltage being greater than the threshold voltage.
